| description | In this paper, we proposed a novel Fabry-Perot cavity antenna with high-gain radiation over two wide bands based on a partially reflective metasurface. To satisfy the resonance condition of the dual-wideband Fabry-Perot cavity, we constructed the unit cell of the partial reflection metasurface by loading magnetic coupling enhancement layers and etching the bottom patches. The partial reflection metasurface composed of the above unit cells can generate reflection phases of positive gradient with almost the same slope over two wide bands, where the partial reflection amplitude is close to 1. Subsequently, a normal dual-band microstrip antenna has also been designed for excitation. Finally, the Fabry-Perot cavity antenna consists of the proposed partial reflection metasurface and the dual-band antenna has been simulated, fabricated, and measured in a microwave anechoic chamber. Both simulation and experimental results demonstrate that the designed Fabry-Perot cavity antenna achieves 3-dB gain bandwidths of 20.7% and 10.1% with peak gains of 12.07dBi and 13.5dBi over two wide bands of 5.7–6.9GHz and 11.7–12.95GHz, respectively. |
